I was going to post something like this a couple weeks ago, but realized that my ideas are too complicated. And also that most people, myself included, wouldn't want their own original ideas done by someone else.
But lucky for you I feel like improvising a few.
- Airport
- Some remakes of some levels of the "Ratchet and Clank" games.
- The Death Star. Someone already did the Star-Trek ship, we have to have SOME dedicated fan-boys out there. :D
- Human Digestive System
- Torn-up space ship perpetually flying through space.
- Ship in a bottle. Scale would be a factor here. :D
Thats all i could think of in 2 minutes.
Ideas are easy, its the follow-through and not getting discouraged thats the hard part.
